Algorithms and strategies to help judges rule cases
Genuine success in this area would be beyond the state-of-the-art in research, since it likely requires analogising from relational knowledge extracted from text. In recent years, techniques for working with natural language have tended to be statistical, and are therefore somewhat deficient in this respect. You could look at 'bag of words'/latent semantic analysis approaches, but they are likely to generate many false positives unless a lot of ad hoc conditions are added manually. More recent work on 'treenets' (paper here) is more structurally informed, but is still a relatively new area.
